A new law recently passed in France mandates that all new buildings that are built in commercial zones in France must be partially covered in either plants

Benefits of Green Roofs

There are so many benefits to green roofs. Here are just a few:

• Adding natural beauty and major aesthetic improvement to buildings, which in turn increases the investment opportunity.
• Helping contribute to landfill diversion by prolonging the life of waterproofing membranes, using recycled materials, and prolonging the service of heating, ventilation, and HVAC systems through decreased use.
• Green roofs assist with storm water management because water is stored by the substrate, then taken up by plants, and thus returned to the atmosphere through transpiration and evaporation. They also retain rainwater and moderate the temperature of the water and act as natural filters for the water that does run off. They delay the time at which runoff occurs, which results in decreased stress on sewer systems during peak periods.
• The plants on green roofs do a great job of capturing airborne pollutants and other atmospheric deposition. They can also filter noxious gasses.
• They open up new areas for community gardens, commercial and recreational space in busy cities where this space is generally quite limited.

France is definitely on the right track, but it should be a mandate that all new buildings being built in North America, and even worldwide, adopt this amazing idea to reap all of the potential benefits.
